Just saw a note on Hilary Stone Cycles facebook page that most Roy Thame frames were built byTommy Quick. Looking at either of the frames in this thread that seems likely to me but I am getting out of my depth here. Quality build in any case. Right now HS is having trouble with his website, if you go to FB just scroll way down until you hit the Thame. Hilary would know just a lot about these frames, unfortunately he charges $$ for a full report.
